The Inventor and Applicant/Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Lavandula plant, botanically known as Lavandula angustifolia, commonly referred to as Lavender and hereinafter referred to by the name ‘Dolavladivivi’.

The new Lavandula plant is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program was to develop new unique Lavandula plants with long flowering period and attractive plant form and flower coloration.

The new Lavandula plant originated from a cross-pollination in April, 2015 of a proprietary selection of Lavandula angustifolia identified as code number LV-0077, not patented, as the female, or seed, parent with a proprietary selection of Lavandula angustifolia identified as code number LV-0052, not patented, as the male, or pollen, parent. The new Lavandula plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Aalsmeer, The Netherlands in April, 2016.

Asexual reproduction of the new Lavandula plant by terminal cuttings in a controlled greenhouse environment in Aalsmeer, The Netherlands since June, 2016 has shown that the unique features of this new Lavandula plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Lavandula have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of the new Lavandula plant. These characteristics in combination distinguish ‘Dolavladivivi’ as a new and distinct Lavandula plant:

-   -   1. Upright to somewhat outwardly spreading and uniform plant         habit.     -   2. Moderately vigorous growth habit and rapid growth rate.     -   3 Freely branching habit.     -   4. Early and freely flowering habit.     -   5. Strong violet-colored flowers positioned on strong peduncles.     -   6. Good container and garden performance.

Plants of the new Lavandula differ primarily from plants of the female parent selection primarily in flower size as plants of the new Lavandula have larger flowers than plants of the female parent selection.

Plants of the new Lavandula differ primarily from plants of the male parent selection primarily in flower bud color as plants of the new Lavandula have violet-colored flower buds whereas plants of the male parent selection have bluish purple-colored flower buds.

Plants of the new Lavandula can be compared to plants of the Lavandula angustifolia ‘Aromatico Blue’, not patented. In side-by-side comparisons, plants of the new Lavandula differ primarily from plants of ‘Aromatico Blue’ in plant size as plants of the new Lavandula are taller than and not as compact as plants of ‘Aromatico Blue’. In addition, plants of the new Lavandula flower earlier than plants of ‘Aromatico Blue’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Lavandula plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Lavandula plant.

The photograph is a side perspective view of a typical flowering plant of ‘Dolavladivivi’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 17-cm containers in Aalsmeer, The Netherlands during the summer initially in a glass-covered greenhouse and finished in an outdoor nursery and under conditions and cultural practices which approximate those generally used in commercial Lavandula plant production. During the production of the plants, day temperatures averaged 21° C. and night temperatures averaged 15° C. Plants were 23 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Second Edition, except where general terms of ordinary dictionary significance are used. Measurements represent averages for typical flowering plants.
